Early Life and Career Beginnings
Seo Kang-Joon was born October 12, 1993, in Suncheon, South Korea. You might be wondering how a small-town boy transitioned to the Seoul spotlight so quickly. The truth is, his passion for performance emerged early.
At age 19, he debuted under Fantagio Entertainment. Early roles in minor sitcoms and music videos paved the way for steady growth. By 2014, he secured a supporting part in high-rated dramas.
Concrete Example: His cameo in “High School King of Savvy” (2014) hinted at a promising future. Critics noted his screen presence—even with limited lines. In other words, he stood out.
